A skip-the-line ticket to the aquarium on Barcelona's old harbour, taking in the Mediterranean galleries and the long underwater tunnel through the Oceanarium.
Most large aquariums are organised around the tropics, because tropical fish are bright and photograph well. This one is built around the sea directly outside the building, which almost nobody does.
More striking is how the tanks are labelled. Rather than grouping fish by type, a series of them recreate specific, named stretches of the Catalan and Spanish coast: the Medes Islands, the delta of the Ebro, the submerged caves of the Costa Brava.
That changes what you are looking at. These are not abstractions of "the Mediterranean" but portraits of identifiable places, most of them within a few hours of where you are standing. You can go and swim in several of them.
The centrepiece is a transparent passage running through the main tank, long enough that walking it takes a while and the water closes completely over your head.
The tank it passes through is stocked as a working section of Mediterranean sea rather than a global mixture: rays, moray eels, ocean sunfish, and two shark species that genuinely live off these coasts.
That last point tends to land with people. The sharks overhead are not exotic imports — they are local animals, in the same body of water that the beach outside the door belongs to.
Be realistic about the register. This is a family attraction on a busy waterfront, not a research institution, and at weekends and in holiday periods it is loud and full of children.
The Mediterranean tanks are also, frankly, less immediately dazzling than a tropical reef display. Grey-green water and grey-brown fish are what the sea here actually looks like. If you go in wanting colour you may be disappointed; if you go in wanting to understand the water Catalonia sits beside, it is the better exhibit.
Your booking gets you past the ticket queue. It does not thin the crowds inside, and the tunnel in particular moves at the speed of whoever is in front of you.
The whole visit is indoors and level, which makes it a sound option in bad weather and a straightforward one with a pushchair.
Early on a weekday is markedly quieter than any weekend hour, and the difference at the tunnel is considerable.
Open it to pick a date and work out the price.
What the fare covers, and what to budget for separately.
The practical detail, and the answers people actually ask for.
It is built around the sea immediately outside rather than the tropics, which very few large aquariums choose to do.
Somewhere you could drive to. Each is modelled on a stretch of shoreline that exists, with a name and a postcode.
Because they are real, identifiable places within reach of the city, and you could go and swim in several of them.
Eighty metres, which is long enough that the water closes over you completely and walking it takes a while.
No. The two species in the main tank live off these coasts naturally, in the same water as the beach outside.
Honestly, no. Grey-green water and grey-brown fish are what this sea genuinely looks like.
It gets you past the ticket queue only. The tunnel still moves at the pace of whoever is ahead of you.
Early on a weekday. The difference from any weekend hour is considerable, especially at the tunnel.
